What Does P1249 Code Means On 7.3L Powerstroke?
When the 7.3L Powerstroke detects that the turbo has been over-boosted, the Diagnostic Trouble Code (DTC) P1249 is triggered. This code indicates that the Powertrain Control Module (PCM) has detected a Wastage Control Valve Performance issue, as this valve’s primary purpose is to allow excess gases of the turbo to bypass and reduce boost levels. The code P1249 signals an inability for the wastegate valve to open and thus reducing turbo boost – resulting in an over-boosted condition.
Symptoms Of Getting The P1249 Code On 7.3L Powerstroke
The P1249 code is not usually correlated with any noticeable symptoms in most cases. However, it has been reported that there are certain occurrences where the DTC P1249 can manifest itself through a few distinct signs.
- Plastic rings around the front (left & right) hubs have become loose.
- The driving experience has been rough and sluggish.
All that should be observed are the specified symptoms, and nothing else.
Causing Factors Of The Code P1249 Error On On 7.3L Powerstroke
Error code P1249 has been identified to be caused by a number of possible factors. Amongst them, the most frequent occurrences have been attributed to a mix of technical issues.
- Damaged Wastage Control Hose Solenoid, Actuator & Valve
- The Wastage Control Hose or Port is Plugged
- The Fuel Injector Harness is Shorted or Open
- Poor Electrical Connection Of Fuel Injector
- Using Performance Chip (Example: A 40HP Super Chip)
- There’s A Leakage In The The Intake Air System
- Damaged Powertrain Control Module (PCM)
Diagnosing the cause of a P1249 code 7.3 Powerstroke can be tricky, as some causes are more serious than others, so it is important to accurately identify the source before becoming too alarmed.
How Serious Is Code P1249 On 7.3 Powerstroke?
While the possibility of a Powerstroke engine being damaged by the P1249 code is almost non-existent, it should not be disregarded as there is still a fragile chance that one may experience extreme engine problems such as sluggish and rough trips. Therefore, to avoid the risk of further complications, it is highly recommended to address this issue upon detection and take the necessary steps outlined in the subsequent section for resolution.
How To Solve P1249 Error Code On 7.3L Powerstroke?
Execution of a removal operation requires the necessary equipment; it is not advisable to attempt such an action bare-handed. Once equipped, one should then proceed with the recommended troubleshooting method for resolving error code P1249, which includes testing whether the component can hold a vacuum properly.
Check The Wastegate Control Hoses
Starting the process, it is important to check the WasteGate Control (WGC) hoses. The red hose should be disconnected from the actuator of the WGC hose. Following this step, a Gauge Bar 014-00760 vacuum pump should then be installed and tested for whether or not it holds a vacuum.
Depending on the outcome, alternate testing may be necessary; for instance:
- To ensure the vacuum is functioning properly, one should inspect the intake port of the hose.
- To determine if the hose is holding optimal suction, it is necessary to check the intercooler port.
Check The Intake Port
Detaching the red hose from the charge air cooler housing should be done first. Testing should then be rerun and actions taken based on the results of this test.
- If the hose holds vacuum: The WGC hose is faulty and needs to be replaced in order to solve the code. Doing so should resolve the issue.
- If the hose doesn’t hold the vacuum: The air cooler is clogged, and to resolve the P1249 code it must be cleaned. Following this step should solve the issue.
Check The Intercooler Port
The task of disconnecting the red hose from the charge air cooler housing and installing the Gauge Bar 014-00760 vacuum pump to the port is completed.
The test is now being run to verify if the actuator can maintain a vacuum:
- If the hose holds vacuum: The intercooler ports are plugged, and require proper cleaning in order to eradicate the code. If this is done correctly, it should result in the permanent elimination of the code.
- If the hose doesn’t hold the vacuum: The presence of an issue with the actuator leads to a necessary investigation. It is suggested that one examines the actuator in order to better ascertain the cause of its malfunction.
Check The Actuator
The Gauge Bar 014-00760 vacuum pump must be installed on the wastegate control actuator as part of the standard component inspection. Following installation, it is necessary to verify that the actuator can hold a vacuum.
- If the actuator holds a vacuum: Regularly checking and installing new WGC linkage is an important step to maintain the optimal performance of a system. Doing this should also resolve any error code P1249 that may arise.
- If the actuator does not hold vacuum: The diagnosis indicates a faulty actuator. Replacing the actuator should resolve the issue.
Check & Replace Powertrain Control Module: The Last Path
When all other potential causes of trouble codes have been eliminated and the DTC P1269 continues to appear, replacing the powertrain control module (PCM) is often the only solution. It should be noted that this option is costly and should be considered a last resort; it is important to exhaust all other possible solutions before opting for this course of action.
Common Mistakes While Solving The P1249 Code
As a newbie to the 7.3L Powerstroke, one may encounter several mistakes while solving this code. It is important to be aware of and avoid these common mistakes that could be made.
- Not Using Necessary Equipment While Executing The Operation
- Not Checking Connectors, Wirings & Everything Else Before PCM
- Additional Comments To Consider Regarding The P1211 Code
P1249 is a common code that appears when a performance chip has been installed, and unless there are visible signs of engine trouble, no need to panic. It is advisable to inspect the cause before investing time and energy into resolving the issue.
This article has provided a satisfactory answer to any queries regarding the P1259 code 7.3 Powerstroke. The decision is left up to the reader whether they wish to take further steps in addressing this issue or if they choose to ignore it until performance issues arise.
